Access control system design document

Access control safety management system is a new modern safety management system which integrates microcomputer automatic identification technology and modern safety management measures. It involves many new technologies such as electronics, machinery, optics, computer technology, communication technology and biotechnology. It is an effective measure to solve the entrance and exit problems of important departments and realize safety management. Suitable for all kinds of security departments, such as banks, hotels, computer rooms, armories, confidential rooms, offices, intelligent communities, factories and so on. With the rapid development of digital technology and network technology, access control technology has also developed rapidly. The access control system has already surpassed the simple doorway and key management, and gradually developed into a complete access control management system. It plays an important role in administrative work such as safety of working environment and attendance management. On the basis of this system, corresponding auxiliary equipment can be added, such as elevator control, vehicle access control, property fire monitoring, public security patrol management, catering charge management, etc. And truly realize the intelligent management of the regional one-card system. In this paper, I outlined my double design work-the design of the access control system in the laboratory. The design here uses a lot of hardware design knowledge of single chip microcomputer, such as LCD display, the use of calendar clock module, serial communication and interrupt design. Please refer to; > The lower computer (single chip microcomputer) can run independently without the permanent support of the upper computer (PC), and the check-in data is stored in the simple www.shlunwen.com database designed by the lower computer. The design of the upper computer is simple by VB and database programming. The function of the upper computer is to send some commands to the lower computer, so as to adjust some running states of the lower computer, take out the check-in data from the lower computer, and inquire about the attendance of personnel entering and leaving the upper computer. The access control system can be used in all kinds of access control systems that are not connected to the internet with a little modification. In the first chapter, some access control systems in the current industry are briefly introduced in order to have a more detailed understanding of the development of the current access control system. The second chapter analyzes the needs of the design topic, so that everyone can have an overall impression of the design goal. The third chapter briefly introduces the experimental and development environment. The fourth chapter briefly introduces each module. Please refer to the technical documentation; & gt。 The fifth chapter is the overall design.
